A prediction model of financial fraud of listed companies based on machine learning method is proposed to predict financial fraud of listed companies. Using the data set of Chinese listed companies from 2000 to 2020 as observation samples, Benford's Law, LOF local anomaly method and SMOTE oversample were adopted, grey samples were excluded, and characteristic variables were selected from five aspects: fraud motivation, solvency, profitability, cash flow and operating capacity. The financial fraud identification model Xscore is established based on the XGBoost method. The Xscore model can improve the accuracy of model prediction, and is superior to the Fscore model and Cscore model in accuracy, recall rate, AUC index, KS value, PSI stability, etc. It is more suitable for predicting the financial fraud of listed companies in China. The results of this study are helpful in promoting the research and application of artificial intelligence and machine learning in accounting, and provide references for promoting the disclosure of high-quality financial information by listed companies and maintaining the order of the capital market.

Vocational education is constantly developing, the proportion of China's education industry is increasing, the number of students is also increasing, coupled with the continuous improvement of the overall education level, leading to the heavy teaching management of vocational colleges in China, leading to the increasing workload and the difficulty of management. In order to adapt to and meet the development of The Times, we should combine the current rapid development of computer technology, optimize the teaching management mode of vocational colleges themselves, and comprehensively promote the teaching reform and development of vocational colleges. This paper mainly analyzes the specific application of computer technology in the comprehensive optimization of teaching management in vocational colleges, hoping to promote the development and improvement of teaching management in vocational colleges in China.

This paper conducts the discussion on the role of the computer technology in promoting students’ Interest in learning. Students’ interest in learning is constantly evolving from low to high levels, through fun, fun and interest in three stages. In interesting stages, the interest of the student is associated with the external characteristics of the stimulus, such as the interest of the novel and interesting teaching content, and when these factors disappear, the interest will soon drop or even disappear. In the computer aided teaching process, the advancement independent study mechanism founds, this time the student community is regarded as the teaching main body, becomes the study the master, the student may act according to own study progress condition to carry on the content repetition study. From this perspective, this paper proposes the novel idea that will later promote the further development of the related subjects.

In the 21 st century in China, multimedia technology and network technology have changed social production and development model and have also changed people's life style and learning style. computer technology not only promotes knowledge economy development in our country, improves international competitiveness in China, but has a huge influence on the education domain of our country. computer technology effectively expands the research field, methods and using range of math subjects, and has become a bright spot and innovation in advanced mathematics teaching reform in our country. This article focuses on advanced mathematics teaching reform under the background of computer technology. Advanced mathematics teachers should realize the necessity of the combination of computer technology and advanced mathematics teaching reform, and starting from the theoretical analysis combined with both sides, put forward the strategies method of the combination.

Application-oriented art academies are professional institutions in which high importance is attached to the training of skills, and play a great help in the improvement of art majors' ability to apply professional knowledge. The establishment of a practice-oriented educational plan is an educational demand on the skills training of art majors. Studio system is one of the very important systems in the educational management of the application-oriented colleges and universities. In this paper, new ideas about the construction of studio system are first elaborated, and then the functional characteristics of computer applied to studio system and the innovation flow of studio system based on computer technology are analyzed. It is hoped that this paper can be helpful for the follow-up studies.
